Cat 5 on 66 block question, need to extend/splice drop......

[Go-To Gordon]

I have a client that I will be running a few new data drops for, terminating wall plates etc. I have no issues with this.

They also have one phone drop that they need to extend. In the network closet they have an old 66 block with all the phone wiring (cat5e). One drop (connected to the 66 block) goes under ground to a building about 100 feet away. They had a phone there and it worked just fine. They now built an office in the back of the building and want to move the phone there. The cat 5 has been cut and the phone removed so I need to splice into that to run a new drop in building 2.

My question is should I just use cat 5 junction boxes like you would for data? I'm not sure how it's wired to the 66 block so wasn't sure how to handle the splice. If I use a junction box I then just wire the 2 blues on the phone jack end?

If it's anything beyond this I have a phone guy I can send them to. Just thought if it's easy enough I could take care of it while I'm there doing the data stuff.

If there's a patch panel port available, wire it as a normal data connection. To connect the phones, make your own wire with an RJ11 (into the port) and the other end connected to the 66 block.

There is no patch panel in building 2. It's literally one cat 5 coming out of the ground at one end of the building. The office is at the other end about 100 feet away. That one cat 5 goes out the building, underground to building 1 where it is already terminated into the 66 block. So I need to tie the 2 drops together to get to the office at the other end of the building.

That's why I was thinking of using a junction box.

Put a crystal on one side of the splice and a keystone jack on the other side. Using a 66-block is a no-no for data. They also make junction boxes just for this reason.

Crystal?

The office side will go to a keystone.

Not for data, for phone.

The junction box you linked to is what I'm planning on using.

A crystal is short for a Modular Plug.

If it's only for a phone line then that junction box is overkill.

What would you recommend for the splice then? Scotchlok?

I've used Scotclok's (red conn) before but only for automotive or other mechanical uses. I see the voice guys use only B connectors (blue conn) or UY connectors (clear/orange conn) for splicing. No need to strip the wires. The connectors have built in teeth that pierce the cable when you squeeze them shut with a pair of pliers and some have a gel which help waterproof the splice. I prefer the UY connector because you can see the wires before you crimp them.

I use the UY connectors and you can buy them all over. I only use the B connectors for alarm stuff.

The Scotch lock's are fine. I've also used the Dolphin ones are well. They have 2 versions. One with gel and one without.

 

[Mercenary Roadie]

I've started using these Beldin 709 series of connectors as they do both wires in a pair at the same time.

 

[Go-To Gordon]

Thanks everyone! I picked up some UY connectors.

I hope the cat5 has a building entrance protector on one end. Sounds like a target for a lightning strike. Personally since this is a permanent extension, I would use either a small 66 block (which gives you a test point should the underground part fail) or use that CAT5e splice block as linked earlier. Much cleaner install.
